What do you think about biofuels production?

There is a place for bio fuel production. The current sources ( primarily corn but other grain as well ) are not very feasable or sustainable in long term. There is promise in development of other sources. Here in Oklahoma and elswhere switchgr is being develooped. It has an advantage in that it can be grown on marginal land that is not currently suitable for food crop production.It also requires fewer resources like fertilizer or weed and pest management.
